Concentration-dependent inhibition by warfarin, Z3, Z5 and CM on adhesion of HCT116 to HUVECs.
(a) warfarin, CM, Z3 and Z5 interfered with adhesion of Rhodamine 123-labeled HCT116 cells to HUVEC monolayer stimulated by IL-1β (1 ng/mL). (b) quantitative analysis of the concentration-dependent effect of warfarin, CM, Z3 and Z5 and warfarin on adhesion of HCT116 cells to HUVECs. Bars represent the mean ± SEM (n = 3). *P < 0.05 and **P < 0.01, compared with the control.
